A couple of years ago I found out a childhood friend has severe kidney disease. He is forced to go for blood transfusions once a day, and only recently, his treatment has helped his health to the point where he can be considered to receive a kidney transplant.
The kidney, liver and lung can all be donated while you are still alive. Would you ever consider donating an organ, or part of an organ while you are still alive?

I've been considering it, assuming my friend and I are the same blood type. At the same time, I think the idea is insane, I haven't physically spoken to him since we were teenagers, but after my own stint in hospital I can't imagine allowing someone to suffer when I have the means to help.
